To all 107mm t may conce/rn.'

Be it kno-wn that I, Gnonon Il. TULLY, a citizen ot the United States,residing at Southbridge, in the county of IVorcester and State ot'Massachusetts, have invented certain new and useful Improvements inTrial-Frames, of which the following is a speci tication.

My invention relates to improvements in trial frames, spectacles and thelike, and has for its principal object the provision of an improvedt'orm ot adjustable temple for use upon trial frames.

The further object o'l' my invention is the provision ot' a templeparticularly adapted for use upon trial frames which will be soconstructed as to permit ot adjustment of the temple relative to theremainder of the frame to suit the requirements ot the individualwearer.

Other objects and advantages of my invention should be readily apparentby ret'- erence to the following description taken in connection withthe accompanying drawings, and it will be understood that I may make anymodifications in the specific details of construction shown anddescribed within the scope of the appended claims without departing fromor exceeding the spirit of my invention.

Figure I represents a view of a trial trame with my improved templesapplied thereto. Fig. II represents a detail view of one form of mytemple. Fig. III represents a detail view et a different form thereof.Fig. IV represents a sectional view on the line IV-IV of Fig. II. Fig. Vrepresents an enlarged detail view illustrating a modified construction:for locking the adjustable portion of my temple in desired position.Fig. VI represents a sectional view on the line VI-VI of Fig. V. Fig.VII represents a perspective view of the rear portion of my temple, andFig. VIII represents a view off a slightly different means for securingthe parts in adjustel position.

In the drawings, in which similar characters of reference are employedto denote corresponding parts throughout the several views, the numerall designates'the main portion of the trial frame having at each end anend piece 2 to which is pivoted the end 3 of the temple section 4, saidtemple member being composed of one or more parts as desired, in certainof the views I having illustrated an ordinary construction ot' trialtrame temple which may be adjusted to vary the length thereof, saidtemple terminating in the arm which preferably projects upwardsubstantially at right angles to the main portion ot the temple.

Slidably mounted upon the arm 5 is a sleeve 6 bearing the car hook 7. Inthe majority of views I have shown the arm fl as disposed at the rearend of the temple. In Fig. III, however, I have shown this arm asdisposed adjacent the end piece 2, its 'function in either positionbeing the same.

The purpose oit my invention should be readily apparent to allconversant with eyeglass fitting by reference to the accompanyingdrawings and it will be understood that the sleeve (5 being adjustableon the arm 5 permits of movement of the ear hook relative to the templeand in this manner car hooks may be accommodated to ears ot dif- 'ferentheights or to cases where the ear hooks need to be raised relative tothe trial frame to insure correct fitting of the lrame on the `face.

I find it desirable in the use of my invention to provide some means forlocking or holding the sleeve and car hook in adjusted position relativeto the temple section. In Fig. IV I have shown this adjusln'lent assecured by means of a thumb screw threaded through the sleeve andadapted to clampingly engage the arm 5, said thumb screw 8 having theinner end thereof burred to prevent accidental withdrawal thereof fromthe sleeve.

In Figs. V and VI in place of employing the thumb screw I have securedto the arm 5 the spring strip 9 having the bosses 10 formed thereon forengagement in the aperture 11 formed in the sleeve, the resiliency ofthe strip 9 :forcing the bosses outward to engage the aperture in thesleeve while permitting of manual sliding of the sleeve as desired.

In Fig. VIII I have shown a still further modification of locking meansin which I employ a spring pressed catch or bolt 12 which may eitherclampingly engage the arm 5 or may lit into any one of a plurality otapertures formed in said arm to receive the end o't the pin as isclearly shown in the drawings.

From the :foregoing description the construction and use of my improvedtemple for trial frames or spectacles should beL readily appar-ent, it:will be seen that I. have provided a simple, durable, eeent and readilyadjustable temple in Which the ear hook portion is adjustable relativeto i verent heights on the head or when the,

patient is suffering from any other mal-y formation.

I claim:

l. The combination Witha temple side having an angular portion at oneend there. of, ofV an ear hook'having an angular pore tion adjustahlyengaging the angular por-A tion of the side.

2. rThe combination with a temple side having an angular portion at oneend there1 Genies of this patent. may he attained .forwfvve gente'addressing the Commissioner of Patents,-

tion of the side, a Clamp for securing 25 the parts in relativelyadjusted position.

3.*The combination With a temple side7 of an ear hook slidably supportedthereby for vert-ieal adjustment relative thereto.

4.. The combination with a temple side, Qt 30 an ear hook verticallyVadjustable relative thereto, and means for securing the parts indesired adjusted position.

5. The combination With a side see-tion, of an angular arm carriedthereby, ran ear hook adjustablymounted on saidarm and means forsecuring the ear hook in adjusted position on the arm.

In testimony Whero I affix my signature in presence of tvvo Witnesses.
